Answer:
The truck travels 40 miles per hour.
Step-by-step explanation:
[tex] \frac{2400 \: miles}{60 \: hours} = \frac{x}{1 \: hour} \\ \\ \frac{60x}{60} = \frac{2400}{60} \\ \\ x = 40[/tex]
It takes about 14 person-hours of labor to break up a driveway and clear away the rubble. It takes about 8 person-hours of labor to pour and smooth concrete for the new driveway.
Answer: 22 person-hours
Step-by-step explanation:
It takes 14 hours to break up the driveway and then to clear away the rubble.
Then it takes 8 hours to pour the concrete and smooth it.
Total time it will take to break up a driveway, clear away the rubble, pour the concrete, and smooth the concrete will therefore be;
= 14 + 8
= 22 person-hours

Which expression is equivalent to -9a-10-6a+7−9a−10−6a+7
Answer:
−30a−6
Step-by-step explanation:
Let's simplify step-by-step.
−9a−10−6a+7−9a−10−6a+7
=−9a+−10+−6a+7+−9a+−10+−6a+7
Combine Like Terms:
=−9a+−10+−6a+7+−9a+−10+−6a+7
=(−9a+−6a+−9a+−6a)+(−10+7+−10+7)
=−30a+−6

The length of each side of a square is 6 feet more than the length of a side of a regular Octagon. The perimeter of the square is equal to the octagon. Find the length of the square and the length of a side of the octagon.
Please show work, I will give brainliest.

Answer:
square: 12 ft sidesoctagon: 6 ft sidesStep-by-step explanation:
This problem can be worked in your head.
If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.
__
We can let s represent the side length of the octagon. Then we have ...
8s = perimeter of octagon
4(s +6) = perimeter of square
These are equal, so ...
4(s +6) = 8s
s +6 = 2s . . . . . . divide by 4
6 = s . . . . . . . . . . subtract s
The octagon has 6-ft sides; the square has 12-ft sides.

Find X (Its a circle question, PLEASE HELP)
Step-by-step explanation:
Since angles in the same segment are equal, Angle ABC (x) = Angle AOC.
Since Angles AOC and COD are supplementary, Angle AOC = 180° - 130° = 50°
Therefore x = 50°.
a number x divided by 4

Step-by-step explanation:
Nichole gets paid $13 and hour washing cars.
A) create an equation that models nicholes pay where x is the number of hours and y is the pay.
B) What is the slope? what is the intercept of the equation?
Answer:
A) y = 13x
B) Slope is 13, intercept is 0
Step-by-step explanation:
Answer:
y = 13x
The slope is 13
The y intercept is 0
Step-by-step explanation:
Since he gets $13 per hour, his pay can be represented by 13x, as x is the number of hours.
To create the equation, set this equal to y, as it represents his total pay.
So, the equation is y = 13x.
Using the equation y = mx + b, we can find the slope (m) and the y intercept (b)
Since this equation has 13 as the coefficient, the slope is 13. There is also no b value since nothing is being added to 13x, so the y intercept is 0.
If BC = 3x, CD = 7x, and BD = 10, what is BC?
Answer:
BC= 3
Step-by-step explanation:
Suppose a line BD is 10 and it has a point C somewhere on the line. It is given that BC is 3times and CD is 7 times or algebraically if we take x as a variable then according to the given information
BC+ CD= BD
3x+ 7x= 10
10x= 10
x= 10/10
x= 1
3x would give 3 (1)= 3
Hence the Line BC = 3
and the line CD= 7
Find the equation of the line.
Use exact numbers
Y=
Answer:
[tex]y=-\frac{3}{2} x+3[/tex]
Step-by-step explanation:
The slope (m) is [tex]-\frac{3}{2}[/tex] by finding the rise (the change in y ⇒ ∆y), over the run (the change in x ⇒ ∆x) from any two points from the line. In this case, the rise is -3, and the run is 2 OR you can say that the rise is 3, and the run is -2.
The y-intercept (b) is 3 because it’s where it intersects the y-axis. If you see the image, you can see that the line intersects the y-axis at the point (0, 3). So, the y-intercept (b) is 3.
Put it all together in Slope-intercept form, which is y=mx+b. So the m (slope) is [tex]-\frac{3}{2}[/tex] and the b (y-intercept) is 3. Plug those in to get: [tex]y=-\frac{3}{2} x+3[/tex]

y = 2/3x - 3 as a function
Answer:
∫(x) = [tex]\frac{2}{3}[/tex]x - 3
Answer:
f(x)=2/3x-3
Step-by-step explanation:
f(x) is the same as y, so the function would be f(x)=2/3x-3.

In a survey, 27% of the people chose salads over a meat dish. In all, 81 people chose salads. How many people were in the survey?
Answer:
300
Step-by-step explanation:
Let x be the number of people in the survey
81/x = 27%
81/x = 0.27
x = 81/0.27
x = 300

Answer:
$2 per Chicken and $9 per Duck
Step-by-step explanation:
the equations for the problem are as follows (x = the value of chickens and y = the value of ducks):
5x + 3y = 55
4x + 3y = 53
if you subtract the equations you would get x = 2, which means the chickens are worth $2 each
If we re-input the x that we now know as 2 and solve one of the equations for y, we will get y = 9
Answer:
If you need the cost of each duck and chicken it would be around 6 dollars per duck or chicken.
